Introduction
This document forms part of a series of European Standards, written by CEN/TC 350, that provide a
system for the sustainability assessment of buildings and civil engineering works using a life cycle
approach. The sustainability assessment quantifies aspects and impacts to assess the environmental,
social and economic performance of buildings and civil engineering works using quantifiable indicators
measured without value judgements. The purpose of this series of standards is to enable comparability
of the results of assessments. This series of European Standards does not set benchmarks or levels of
performance.
This series of standards will allow the sustainability assessment, i.e. the assessment of environmental,
social and economic performance of a builings and/or civil engineering works, to be made concurrently
and on an equal footing, on the basis of the technical characteristics and functionality of the object of
assessment.
The sustainability assessment of buildings and civil engineering works uses different types of
information. The results of a sustainability assessment of a building and/or civil engineering works
provide information on the different types of indicators, the related works scenarios, and the life cycle
stages included in the assessment.
In carrying out assessments, scenarios and a functional equivalent are determined at the construction
works level. Assessment at the construction works level means that the descriptive model of the works
with the major technical and functional requirements has been defined in the client’s brief or in the
regulations, as illustrated in Figure 1.
Assessments can be undertaken either for the whole building or civil engineering works, for a part of the
works or for a combination of several buildings and/or civil engineering works.
Although the evaluation of technical and functional performance is beyond the scope of this series of
standards, the technical and functional characteristics are considered within this framework by reference
to the functional equivalent. The functional equivalent takes into account the technical and functional
requirements and forms the basis for comparisons of the results of the assessment.
Any particular demands for, or related to, the environmental, social and economic performance defined
in the client’s brief, or in regulations, may be declared and communicated. Figure 1 shows how the
functional equivalent, and the technical and functional characteristics that differ from those required,
either by the client’s brief or through regulations, are to be declared and communicated with the results
of the assessment.

NOTE The outer box with the dotted line represents the area standardized by CEN/TC 350.
Figure 1 — Concept of sustainability assessment of construction works
In concept, the integrated construction works performance incorporates environmental, social and
economic performance as well as the technical and functional performance, and these are intrinsically
related to each other. Although the assessment of technical and functional performance does not form
part of this series of standards, their interrelationship with environmental, social and economic
performance is a prerequisite for an assessment of sustainability of construction works and, therefore, is
taken into account, as illustrated in Figure 1.
The users’ activities associated with the constructed asset (referred to as “users’ activities”) are part of
the assessment of construction works. These can include, for example, the fuel consumed by the cars
users of a road as part of the assessment of infrastructure, or the energy used for commuting to and from
a building, as part of a building assessment.
It is advisable to carry out an assessment at the earliest opportunity during the conceptual stages of a
construction or refurbishment project such as in the initial planning stage in order to provide a broad
estimate of the environmental performance, social performance and economic performance. As the
project evolves, the assessment can be periodically reviewed and updated to support decision-making. A
final assessment (as-built) should be carried out. The results of this final assessment can be used to
inform all parties concerned, and also serve as the database for future new similar projects.

This framework is the general framework for sustainability assessment of buildings and civil engineering
works. The purpose of this EN 15643 is to provide a framework with principles, requirements and
guidelines for the assessment of the environmental, social and economic performance of a building
and/or civil engineering works or combination thereof at the “framework level”. This document has been
drafted by combining the previously publishled 5 parts of the framework standards; i.e. EN 15643-1, −2,
−3, −4 and −5 into one framework standard.

1 Scope
This document provides principles and requirements for the assessment of environmental, social and
economic performance of buildings and civil engineering works taking into account their technical
characteristics and functionality. Assessments of environmental, social and economic performance are
the three aspects of sustainability assessment of buildings and civil engineering works, or combination
thereof, (hereafter referred to as “construction works”).
The framework applies to all types of construction works, both new and existing, and it is relevant for the
assessment of the environmental, social and economic performance of new construction works over their
entire life cycle, and of existing construction works over their remaining service life and end of life stage.
The sustainability assessment of construction works concentrates on the assessment of environmental,
social and economic aspects and impacts of construction works expressed with quantifiable indicators.
It includes the assessment of a construction works’ influence on the environmental, social and economic
aspects and impacts on the local area (area of influence) and of the local infrastructure beyond the
curtilage of the building and the civil engineering works. It excludes environmental, social and economic
risk assessment.
The European Standards developed under this framework do not set the rules for how the different
assessment methodologies may provide valuation methods; nor do they prescribe levels or classes for
measuring performance.
NOTE Valuation methods, levels, classes or benchmarks can be prescribed in the requirements for
environmental, social and economic performance in the client’s brief, construction regulations, national standards,
national codes of practice, construction works assessment and certification schemes, etc.
The rules for assessment of environmental, social and economic aspects of organizations, such as
management systems, are not included within this framework. However, the consequences of decisions
or actions that influence the environmental, social and economic performance of the object of assessment
are taken into account.
